// A DROP ON THE TREE IS FILED WHERE IT WAS DROPPED; a paste into a note keeps
// the attachment setting. The owner dragged a PDF onto Library/ and found it
// in attachments/; later a friend dropped a folder of icons on a folder and
// found them all in attachments/ too. The location setting is for uploads
// that named no place. `uploadDestination` is that distinction as a function.
